There are loads of videos on You Tube, check em out. I prefer a wrap personally but plastidip is a more economic alternative. They have released new colours in can form as well.
I watched a few videos on youtube before I did it, they didnt help at all, and most of them did it the hard way (masking everything off). My advice is buy a can and do it. Its a $9 experiment, if you have enough money to buy a xfire, you have enough for a $9 paint can. If you dont like it, peel it off lol.
